Procurement Notes
Verify the specific suffix TL against official ROHM documentation to confirm tape and reel packaging specifications. Ensure the component meets AEC-Q101 automotive qualification requirements if intended for vehicle-mounted use. Cross-reference the exact part number with manufacturer datasheets to validate RoHS compliance status and lead times prior to procurement.
Selection Notes
Select this component for applications requiring high current handling in a compact surface-mount form factor. The dual anode arrangement allows for flexible circuit topologies. Consider the thermal management capabilities of the TO-263S package when designing heat dissipation strategies for continuous 40 A operation.
Part Context
This device belongs to the RB238NS series of Schottky barrier diodes from ROHM Semiconductor. The series is characterized by low forward voltage and ultra-low reverse current. The RB238NS-40TL specifically targets high-efficiency power conversion needs within the automotive and industrial sectors.
Replacement Considerations
Check for direct substitutes such as the RB238NS-40FH which shares similar electrical characteristics and automotive qualification. Verify pinout compatibility and thermal performance before substituting.
